In applying Vthe invention to the production of a brush such as is shown in sectional view in Fig. 18, .the -knot a, of bristles is treated in the slime way asthat hercinbefore described and illustrated in Figs. 1, 2 and 3 but it is not divided for the reception of a wedge/s described, so that asingle pad f of the vulcanizable material 'is introduced mbo the former c above the cemented ends of the' bristles, as shown in Fig. 14. Fig. lshows the single vulcanizble pad detached. The. `-bristles and pad are then subjected to al vulcanizing heat, as 1n the case previously de-- scribed, und, after the said bristles and the pad have been vulcanized hard together, the former c is removed and the knot is passed through the ferrule y'. shown in Fig. `18, so that the bristles project through` one end the endsof the bristles'.

the bristles or lbers, whereb sity of integrally vnlennlzed oo :he eennent holding Le will be understood that the method of applyingthe invention above described may f varied in accordance with the particular type of brush to be produced, and that'the mode of connecting the bristles to thehandle may also 4be varied, since the essential feature of theinvention consists in the formation of the vulcanized block or pad inte-y gral with the `cement binding the ends of an economy in and the necespassing nails through the bristles is avoided.-

' What I claim and desire ters e the cost of bristles is e'ec to 'secure by Let- Patent 1s:- l The l process of manufacturing brushes which consists in uniting a knot or bunch of applying to the ends of the bristles thus'cenlentcd together a vulcanizable block to form un extension, subjecting the cerne ted ends of the bristles and block to yheat en refesure to vulcanize and cement them tget er, and finally applying a handle to the'said knot of bristles.- 4.
